{"product_id":"jb4-performance-tuner-1","title":"JB4 Performance Tuner","description":"The Kia Stinger \/ Genesis G70 JB4 Performance Tuner is a sophisticated plug-and-play device engineered to significantly enhance your vehicle's performance. It works by integrating with your factory ECU to remap critical parameters like boost pressure, ignition timing, and fuel delivery, resulting in improved power output and a noticeable reduction in turbo lag. The tuner utilizes an advanced CANbus system, allowing it to process a wide array of real-time data, including pedal input, throttle position, gear selection, engine speed, air\/fuel ratio, ignition advance, and knock detection, to optimize performance mapping dynamically.\n\nBeyond raw power, the JB4 incorporates unique safety features to safeguard your engine and turbocharger. It intelligently manages boost pressure, ensuring it remains low until optimal engine oil and water temperatures are achieved, providing proper lubrication. Additionally, it can automatically switch to a lower boost map if the engine experiences overheating, a lean condition, excessive knock, or over-boosting, ensuring the longevity of your powertrain.\n\nThis performance tuner offers exceptional flexibility with preloaded maps for various fuel types, including 91 octane, 93 octane, and E85 (ethanol fuel) mixtures. Users can select these maps on the fly using the JB4PRO free app, available for both iOS and Android devices. The app also provides robust data logging capabilities, allowing for real-time monitoring of up to 40 engine parameters, performance analysis, and firmware updates.\n\nFeaturing a rugged billet aluminum enclosure for durability and protection, the JB4 is designed and assembled in the USA and comes with a comprehensive 5-year warranty. It is compatible with all factory driving modes, and fuel economy remains unchanged during normal driving. It's important to note that 91 octane fuel or higher is required for performance gains, and the unit is not VIN-locked, allowing for easy resale. The manufacturer also suggests upgrading spark plugs if they have more than 25,000 miles when running higher boost levels.","brand":"Kia","offers":[{"title":"Default Title","offer_id":52686461862200,"sku":"BMS-JB4-GENESIS-G70","price":599.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/659227615.webp?v=1784874081","url":"https:\/\/store.motormia.co\/products\/jb4-performance-tuner-1","provider":"MOTORMIA","version":"1.0","type":"link"}
